I've created an account to show my support to this request. I'm tired of my touchscreen keyboard too, especially when chatting in groupchats. I really like AirDroid, the lay-out and usability are great! If you integrate support for Whatsapp then I'll use AirDroid 24/7. It's not a win-win, it's a win-win-win! For AirDroid, Whatsapp and the thankful user of both apps, like me.

It would be great to get a response about this request by the AirDroid team. If they have already done that, please post the link. I've searched for it but I could not find anything.

Nthing all the commenters before me. Whatsapp integration is what made me stumble upon Airdroid in the first place, and I must say I am impressed with it so far. If you can pull it off, hats off to you. +1 for sure.
